Deforestation of the Amazon reached historic highs under President Jair Bolsonaro, who will be replaced in office by Lula in January.
Mr. Bolsanaro, a climate sceptic, claimed that non-governmental organisations (NGOs) had set the Amazon on fire to discredit his government, and he allowed illegal mining to spread throughout the region, including on protected indigenous lands.
An indigenous chief from the largely deforested Pará state named Puyr Tembé told BBC News that Mr. Bolsonaro completely demolished regulations safeguarding the Amazon and assaulted environmental activists.
Lula, on the other hand, has stated that he will work to stop deforestation and restore the Amazon.
